NOTE:

Check codes which are not listed may be indicated, but they cannot be inspected.
The check codes are displayed in numerical order. (While performing the inspection, if you want to inspect a check code with a number smaller than the code number you are currently inspecting, terminate the check mode then repeat the inspection from the beginning.)
If a speed signal is input to the instrument cluster (the wheels are rotated) while a code other than check code 50 or 51 is displayed, the input/output check mode will be cancelled.
The check codes can be fast-forwarded by pushing and holding the odometer/tripmeter switch for 1 s or more .
